- FOUNDATIONS; PA AND OA SET
EXAM WITH 100% CORRECT
ANSWERS 2025
It is a network of users that share computer resources in a limited
area. correct answers >> LAN
Local Area Network correct answers >> LAN
How are Local Area Networks defined? correct answers >> In
terms of protocol and the topology used for accessing the
network.
A set of rules established for users to exchange information
correct answers >> Protocol
The network architecture used to interconnect the networking
equipment. correct answers >> Topology
What are the most common topologies for LANs? correct
answers >> Ring, Bus, and Star
Uses a token that is placed in the data channel and circulates
around the ring. correct answers >> Token Ring topology
,A deterministic network correct answers >> Token Ring
Topology
Each station connected to the network ensures access for
transmission of its messages at regular or fixed time intervals
correct answers >> Deterministic
What are the disadvantages of the Token Ring system? correct
answers >> 1. If an error changes the token pattern, it can
cause the token to stop circulating.
What is a disadvantage of the Token Ring system from the
troubleshooting and maintenance? correct answers >> The
token ring path must be temporarily broken or interrupted if a
computer or any device on the network is to be removed or added
to the network.
What is a solution to the troubleshooting and maintenance
disadvantages of the Token Ring system? correct answers >>
Connect each computer or device on the network to a central
token ring hub.
A device that manages the passing of the token instead of relying
on individual computers to pass it. correct answers >> Token
ring hub
How does the token ring hub improve the network? correct
answers >> It improves the reliability of the network.
, Topology whereas the computers share the media or coaxial
cable for data transmission. correct answers >> Bus topology
The coaxial cable that is looped through each networking device
to transmit data in a bus topology correct answers >>
ThinNet
In this topology, all devices on the network can see each other's
data traffic. correct answers >> Bus topology
Topology whereas each computer must wait for pauses in
transmission or until the transmission from one device is
complete before initiating a new transmission onto the network.
correct answers >> Bus topology
What are the disadvantages of a bus topology? correct
answers >> "1. Data can be corrupted if ore than one device on
the network transmits at the same time and will have to be
resubmitted.
2. The use of the shared coaxial cable prevents data transmission
from being very bandwidth-efficient."
Which topology is seldomly used in modern networks? correct
answers >> Bus topology
What is the most common topology used in today's LANs?
correct answers >> Star topology
